GRAIN-DRIER.

SPECIFICATION forming part of Letters Patent No. 328,788, dated October20l 1885.

Application filed April 2, 1883.

.To all whom, t may concern:

Be it known that I, JOHN C. KLAUDER, a citizen of the United States, anda resident of Philadelphia, Pennsylvania, have invented an ImprovedApparatus for Preparing Corn for being Ground into Meal, of which thefollowing is a specification.

My invention relates to a certain improvement in apparatus for dryingcorn preparatory to grinding the same into meal, the object of theinvention being to so construct the kiln that the thorough drying of thegrain will be effected without scorching the same, and without the useof blast or suction apparatus for causing a draft through the kiln.

In the accompanying drawings, Figure l is a transverse section of thekiln; Fig. 2, a longitudinal section of the same, and Fig.- 3 asectional plan view.

The casing of my improved kiln is in the present instance rectangular,and comprises the opposite ends, a a, and sides b b, the latter beingmade of wire-gauze or perforated sheet metal, suitably strengthened andbraced by external slats, d, so as to resist the outward pressure of thecorn,which is fed into the top of the kiln through a hopper, f, and isdischarged from the lower end of the said kiln by means of a shaft withradial blades g, this shaft being rotated by suitable means at a rate ofspeed proportionate to the speed at which the corn must traverse thekiln.

Centrally within the kiln are arranged two vertical rows of steam-pipes,h It', the ends of which are connected together by short inclined pipesh2, so arranged that the steam entering the top pipe, h, at theleft-hand end, for instance, will traverse the same, then pass throughthe first connecting-pipe, h2, into the right-hand end of the top pipe,7a', then pass through the same to the opposite connectingpipe, hz, andthrough the latter to the left-hand end of the second pipe, h, and so onto the bottom pipe, h', from which it is discharged.

Serial No. 90,251. (No model.)

rIhe space between the rows of pipes h, and the spaces between saidpipes and the sides b of the casing present narrow channels, down whichthe corn is compelled to flow in thin layers in traversing the kiln, sothat the heat from the steam-pipes is caused to act most effectively indrying the corn.

The degree of temperature to which the corn is subjected will dependupon the pressure of steam in the pipes h, and this can be readilycontrolled by suitable valves.

rIhe corn is discharged from the kiln into the trough or box of aconveyor, m, by which it is conveyed to a suitable receptable or to themills. rIhis, however, is not essential.

It will be noticed on reference to Fig. 1 that 6o the kiln occupiesaninclined position. This is an important feature of my invention, as itpermits the escape of the vapors from the upper side of the kiln as theyrise from the mass of corn, whereas if the kiln were vertical the vaporsarising from that portion of the contents of the kiln not actually incontact with the casing would have a tendency to ascend vertically, andwould have to traverse the mass of corn before escaping at the hopper,or else cumbrous and expensive blast or suction apparatus would have tobe employed to cause a lateral draft through the kiln.

I therefore claim as my invention- The combination, in a kiln for dryingcorn, 75 of the inclined casing having opposite perforated. sides, thecentral steam-heated pipes, the feed-hopper at the top, and thedischarging device at the bottom, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN O. KLAUDER.
